 Set resource limit. The rnd_process_events() function is called every tick
and process the sample queue. Without limitation, if a lot of rnd_add_*()
are called, all kernel memory may be eaten up.
Make sure there is enough space for sockaddr subtypes
Use u_char for IP_MULTICAST_LOOP as specified in in.h
Enable and add ls command for ufs.
From:  Steffen "Daode" Nurpmeso:

Amend the previous commit to support zone-style RFC 822 dates.
RFC 5322 marks this zone-style as obsolete (obs-zone), but still supports it.
But then, even if you don't wanna support military style single-letter zones,
the UT zone exists and will not be supported by this commit.

The changes here are not strictly correct (since not all possible
single-letter zones are assigned, and only *UT* has two letters),
but which will match all thre possible *obs-zone* forms.
Compiled and tested on a single MBOX.
don't wait for completion if we were interrupted.
Add UFS2 support.  Also bump version.
tidy up some more by factoring out the sizing code.
Add a new "debug" set that gets built when ${MKDEBUG} is set. On evbarm:
-rw-r--r--  1 root  src   35806068 Jan 16 10:47 base.tgz
-rw-r--r--  1 root  src   57374069 Jan 16 10:48 comp.tgz
-rw-r--r--  1 root  src  101286193 Jan 16 10:49 debug.tgz
...
This allows always building the debugging code and libraries but not
installing it (although now it is placed in the default sets if ${MKDEBUG}
is set
fix misplaced paren
fix some bit #define, now the name actually makes some sense
copy data in 32bit chunks whenever alignment permits
 -> very noticeable speedup
Do the protocol consistency check hack only when compiling ELF.
- add xdebug set
- document debug better
- fix previous debug fallout.
Add some comments to illustrate what is actually happening.
On Cortex, speculative loads can cache lines to be populated after then they've
been invalidated for a DMA read.  So after the DMA read we have to reinvalidate
them again.  We have to both invalidates since the former prevents dirty lines
overwriting just DMAed data.
calc_timer_factors: use supplied ints_per_sec, not hz, when calculating
counter frequency.
- Add support for xsets
- Factor out common evbarm code
don't draw blanks by hand, use the blitter instead
Cortex needs ._dmamap_sync_post for BUS_DMASYNC_POSTREAD
